MISSION BEACH MAN PLEADS TO ROLE IN MASSIVE DRUG RING

Morgan Dimmitt, 27, the only Mission Beach resident who was arrested in a sweeping undercover drug investigation in North County, has pleaded guilty to conspiracy to possess cocaine with intent to distribute.

Dimmitt, a construction worker who now lives with family members in Utah, is free on $75,000 bond. He will be sentenced June 9 in U.S. District Court in San Diego.

Assistant U.S. Attorney Michael Wheat filed a court document indicating he will be seeking a 30-month federal prison term for Dimmitt. His attorney is expected to argue for probation.

A year-long investigation by the Drug Enforcement Administration and the sheriff’s department yielded 65 arrests, mostly in Ramona and Poway, on Sept. 10.

It was called “Operation Mountain Shadow,” and authorities seized 93 pounds of methamphetamine, 56 pounds of cocaine and 14 pounds of heroin. In all, 73 people were rounded up in the sting.

PB GRAFFITI CLEANUP DRAWS AT LEAST 100

More than 100 people showed up to the seventh annual Graffiti Clean Up Day in Pacific Beach this month to demonstrate community dedication and pride. The event is a partnership by the Pacific Beach Town Council (PBTC) and the PB Presbyterian Church.

“We removed more than 800 graffiti tags this year,” said Town Council vice president Adam Meyer. “Although that’s not as much as previous years, it’s good news because every year there’s less graffiti to clean up.”

San Diego Police Chief Shelley Zimmerman has been involved since the beginning. She said cleaning up Pacific Beach helps promote San Diego as a tourist destination.

“The cleanup not only makes the community look nice, but it makes it safe, too,” Zimmerman said. “We’re the ambassadors to the hundreds of thousands of people who come to San Diego every year.”

Other organizers agreed.

“The people we train at this event tend to remove graffiti on their own throughout the year, and that cuts down graffiti overall, because taggers get discouraged when their tags are removed quickly,” said Marcie Beckett, a PBTC member who has been involved in this event from its inception. “Events like this encourage everyone to have more pride in and respect for Pacific Beach.”
